This invention relates to a checking apparatus for use when making sales, making out receipts and the like.

For instance, in the case of sales in shop-s the checking means hitherto generally used consists in this, that the salesman writes out a bill with one or more copies. When there is one copy, the purchaser receives the original as a receipt, the copy being retainecl by the salesman. When there are two copies, the purchaser receives besides the original a copy to be handed in when payment is made at the cash desk, so that a copy is retained both by the cashier and by the salesman. These checking means are, however, not suii'icient, as the salesman may still subsequently falsify his copy or, when there are two copies, the salesman and the cashier may act in connivance and subsequently falsify their copies in a corresponding manner.

In order to make such falsification impossible provision is made according to the invention that the copy retained by the business or one of more copies is made inaccessible to unauthorized persons without this being apparent.

For this purpose the bill with its copy or copies is made out on a continuous strip in an apparatus in whichthe copy strip is gradually wound up while the bill with or without an extra copy is led out of the apparatus and is torn off for being handed to the purchaser. The strips` are automatically cut into each time the apparatus is open and are perforated or marked in some other manner,

driving` means being provided which are connected to the cover of the apparatus and which during the raising of the cover influence a cutter mechanism'in the apparatus in such a manner that the aforesaid marking is effected, which shows clearly that the apparatus has been opened.

One constructional form of the invention is shown in the accompanying drawings, in

Fig. 1 shows the apparatus as viewed from the side, with the cover in section,

Figs. 6 and 7 the arm shown in Fig. 4 seen from the opposite side with the device for cutting the paper webs, in two different positions. o

The apparatus consists of a box 1 formed by the bottom plate 2 and the cover 3. The

Vcover 3 may be fixed as shown in the drawing to the bottom plate by means of hinges or in any other suitable manner. Besides the hinges looking arrangements of a-known kind, such as a. lock, hooks, small bolts Vor the like may be provided. The hinges are usually provided at the front edge in .such a manner that the cover can be raised and the interior made accessible.

Onthe bottom plate 2 walls 4 are provided for supporting a rollV 6 of paper on which the bills are made out. According to requirement the number of strips wound up to form the roll 6 may be two or three or more. In the drawings only two strips are shown for the sake of simplicity.

Instead of the strips being wound to form one roll separate strips may be wound each to form a separate roll journ alled in the walls 4. Such an arrangement, however, takes up more space and consequently makes the apparatus larger.

The roll of paper 6 is suitably wound on a cardboard cylinder, Wood cylinder or the lik`I which is bored for taking a shaft 7. V he shaft can be inserted in or withdrawn from the roll and is fixed by a spring-loaded clamp or the like (not shown) in such a manner that the roll 6 will turn about the shaft 7. For preventing the paper strip unwinding too ra-pidly, the roll 6 can also be provided with braking means, such as Springs or the like, so that a considerable force has to be applied to the paper for causing the roll to turn.

From the roll 6 the collected paper stri ps ets 25 fixed to the writing support 13.

10 and 11 are led to the guiding bar 8 journalled in the walls 4. From there the strip 10 is guided on the upper side and the strip 11 on the under side of a dividing or separating bar 12 at the edge of the table which serves as a writing support. The strips are then guided over the said writing support up to the front edge where a similar separating bar 14 is provided, one strip 10 passing over, and the other strip 11 under the bar 14 in a similar manner as in the. case of the bar 12. Corresponding to the writing surface but somewhat sinaller than the said surface an opening 15 is provided in the cover 3 so that the upper strip may be written on.

The copying is efected in a known manner by a. carbon paper strip being guided over. the writing support between the strips 10 and 11. The carbon paper is wound lile the roll 6 on a cylinder 17 journalled on the shaft 18 in the wall 20. Thence` it is guided below the writing support 13 and then over the edge of the same. From this edge it is introduced between the strips 10 and 11 and travels back over the writing support to the driven reeling up cylinder 21. The latter as will be seen from the drawing is journalled in one of the walls 20 only and follows the motions of the shaft 22.

From the bar 14 at the front edge of the writing support, which bar serves the purpose of separating the paper strips which have been written on, these paper strips are brought together and guided between two rollers 23 and 24. These rollers may be made of rubber, paper or the like and have a fiuted surface for advancing` the paper. The rollers are iournalled in front of the bar 14 in braclr- Preferably they are forced against one another by Springs so that a continuous pressure is eX- erted on the strips of paper 10 and 11 lying between them. On the rollers 23 and 24 two equal toothed Wheels 26 and 27 which mesh with one another are mounted. These toothed wheels ensure the rollers rotating at the same speed. After passing through the rollers, the lower strip 11 (the checking strip) is guided around a cylinder 28, while the upper strip (the bill for the purchaser) is guided over a guide bar 29 and under a spring-loaded cutter 30 up to the front edge of the same. On this cutter being depressed the bill 10 is clainped between the cutter and the extension of the guide bar, is torn off and presented to the customer.

The forward feed of the two strips 10 and 11 is eifected by the cylinder 28, for which purpose the lower strip 11 is fixed to it in any suitable manner. The cylinder is caused to rotate for instance in the direction indicated i n 1 through turning by hand a ley (not shown) ffzed on the shaft 31. The shaft 31 is ournalled in two walls and 33 mounted on the bottom plate 2 and is rotatable in one direction only. On the cylinder 28 being rotated in the direction indicated in Fig. 1, the strip 11 will be put in motion. This motion causes the fluted rubber roller 24 to rotate and, by means of the toothed wheels 26 and 27, the upper rubber roller 23 is also caused to turn. Owing to the fact that the rollers are pressed together by a spring against the strips, the upper strip 10 is moved forward and upwards on the inclined surface of the guiding bar 29, as it is carried along owing' to the friction between the lower strip and the upper roller. The carbon paper is fed forward at right angles to the forward motion of the strips 10 and 11 by means of a worm and wormwheel. On the hand-driven shaft 31 a worm 34 is inounted, which worm ineshes with a worm wheel on the shaft 22 of the carbon paper cylinder 21. Through this feeding arrangement the desired low speed of travel may be imparted to the carbon paper. Normally the apparatus is to be opened only for changing the rolls and on closing down for the day for removing the checking roll 28. 'For notifying any other opening of the apparatus, the following` checling device is provided:

Inside the cover on the longitudinal side thereof a plate 40 (Figs. 3 and. 5) is fixed, which plate supports a sleeve 41 in which a catch 43, which is under the influence of av spring 42, is slidable. To this catch a bow 44 is fixed, the object of which will be described below. The catch 43, the free end of which is cut off at an inclination is adapted to coact with an arin 45 which is keyed on a pin 46 capable of rocking in the frame of the apparatus. On the pin 46 is also keyed a knife-like arrangement 47 (Figs. 2, 6 and 7) with a V-shaped knife edge which is disposed directly above the paper strips 10 and 11. (Figs. 6 and 7 Normally the arm 45 is held by a spring 48 in the pull down. position against a stop 49, causing the lrnife edge 47 to occupy the position shown in Fig. 6. Assuming the apparatus to be opened and with the cover in the raised position the catch 43 will, on the cover being hinged down again, be brought against the arm 45 (Fig. 5) and will be pushed back in opposition to the spring 42 until the cover has reached its closed position, whereupon the catch will spring forward under the arm as is indicated in Fig. 5 by dot and dash lines. Should the apparatus be opened again by hinging up the cover the catch 43 will raise the arm 45, causing the knife edge 47 to rock downwards into the position shown in Fig. 7 and to cut through the paper strips 10 and 11, as indicated by 50 in Fig. 2. By this means a clear indication will be given on the paper strips that the apparatus has been opened. In order to prevent the catch 43 becoining locked in such a position that the cover can be swung upwards and downwards unhindered by the arm 45, the catch 43 is provided with a bow 44 which, should the catch become locked in the position referred to, Will be caused to bear against the rear end of the arm 45 by the cover being swung downwards and thereby make it impossible to close the cover.

Instead of a V-shaped cut being made in the paper strip other shapes may be employed through giving the knife a suitable form, for instance a perforation, a cut in the edge or the like.

What I claim is:

1. A checking apparatus, comprising a cover for the apparatus, which is capable of being opened and closed, means within the apparatus for reeling up the continuous copy strip, an arm pivoted in the apparatus, means for limiting the downward motion of the arm, a knife edge fiXed to the said pivoted arm for incising the said strip, and a springloaded slidable catch mounted on the inside of the cover, capable of being forced aside while the cover is being closed and of engaging under one end of the said arm for taking the arm along with it on the cover being opened, as and for the purpose set forth.

2. A checking apparatus as claimed in claim 1 and comprising a securing bow on the said catch capable of bearing against the other end of the arm When the catch is in the locked position in which it does not make contact with the arm, for preventing the cover being closed, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification.

PETER SOLHEIM.
